The luxury SUV segment continues to evolve with Mercedes-Benz strengthening its position through the arrival of the refined GLS AMG Line in the American market. This sophisticated three-row SUV represents the perfect fusion of Mercedes-Benz’s legendary luxury heritage with AMG’s performance-oriented design philosophy, creating a compelling package for discerning buyers seeking both elegance and sporting character.
Overview of the 2025 Mercedes-Benz GLS AMG Line
The 2025 Mercedes-Benz GLS AMG Line brings a distinctive aesthetic enhancement to Mercedes-Benz’s flagship SUV, building upon the substantial updates introduced in the 2024 model year. This variant carries forward significant design improvements including an updated grille design, a new steering wheel with touch control, and new paint color options such as Twilight Blue metallic and nonmetallic MANUFAKTUR Alpine Grey.
The AMG Line treatment transforms the already imposing GLS into a more visually striking presence on American roads. The AMG Line showcases sportier bumpers with larger air intakes, with wheel arch cladding and side sill panels painted in body colour, unlike the black finish on the regular GLS. This creates a more cohesive and aggressive appearance that appeals to buyers seeking a balance between luxury and sport.
Design and Exterior Enhancements
The exterior modifications represent more than mere cosmetic changes, reflecting a thoughtful approach to performance-inspired design. At the rear, a diffuser-like insert with a thin chrome strip adds to its sporty appeal, creating visual connections to Mercedes-AMG’s high-performance heritage while maintaining the sophisticated character expected from the GLS nameplate.
The AMG Line features distinctive 21-inch AMG twin 5-spoke wheels with black accents, which not only enhance the visual impact but also improve handling characteristics. These wheels serve as a bridge between the standard GLS’s luxury-focused appearance and the full AMG models’ performance orientation.
Interior Refinements and Technology
Inside, the AMG Line features an AMG-spec steering wheel with a twin-spoke design, stainless steel pedals, and floor mats with AMG lettering. These elements create an immediate connection to Mercedes-AMG’s performance division while preserving the luxurious atmosphere that defines the GLS experience.
The cabin continues to prioritize passenger comfort and technological sophistication. The GLS offers truly luxurious seating for seven adults as standard, with a no-charge 6-seat option featuring power 2nd-row captain’s chairs with walk-through 3rd-row access. This flexibility allows buyers to configure the vehicle according to their specific needs, whether prioritizing maximum passenger capacity or enhanced second-row comfort.
Performance and Powertrain Options
Engine Lineup and Capabilities
The GLS AMG Line maintains the proven powertrain options that have established the GLS as a leader in the luxury SUV segment. The GLS 450 starts with a 375-horsepower turbocharged six-cylinder engine, while the GLS 580 features a twin-turbocharged V8 engine with 510 horsepower. These engines incorporate Mercedes-Benz’s advanced hybrid technology for improved efficiency and performance.
Hybrid electrification, a Hybrid Integrated Starter-Generator, an ECO-START system, a 9G-TRONIC 9-speed transmission, and 4MATIC all-wheel drive are standard across the 2025 Mercedes-Benz GLS engine lineup. This comprehensive approach to drivetrain technology ensures that every GLS delivers both impressive performance and respectable efficiency for its size and capability.
AMG GLS 63: The Performance Flagship
For buyers seeking maximum performance, the AMG GLS 63 represents the pinnacle of the lineup. The AMG GLS 63 features a 603-horsepower, 627-lb-ft handcrafted 4.0-liter twin-turbocharged V8 engine with a 48-volt hybrid system. This powerplant enables a sports-car-rivaling 3.6-second run to 60 mph, demonstrating that luxury and performance can coexist without compromise.
